148 THE ORCHID REVIEW. 
to about one-half of its depth, over which place some rough material, and 
then complete with the mixture, which should be rammed in fairly firm. For 
a week or so no water should be given those repotted, and when it is applied 
it should be through a rose for several times, until the surface has settled. 
After sufficient time has elapsed to allow the new roots to enter the fresh soil, 
water should be giver more frequently, but being grown continuously in a cool, 
moist atmosphere, it is wonderful how long they will go without requiring 
a fresh supply at the root. The temperature given to this species here, is 
similar to that generally afforded Odontoglossum crispum, though perhaps 
the house where the Cymbidiums grow becomes a trifle warmer during the 
afternoon, as the blinds are drawn up earlier than on the Odontoglossum 
house, but as far as fire-heat is concerned less is needed for these during the 
winter, as they will stand a much lower temperature than the generality of 
cool Orchids. Two years ago during the severe winter we then had, the 
temperature of this house was exceedingly low, viz., 38° and 40° for over 
six weeks, and for forty-eight hours all our efforts could not raise it above 
34°, yet no harm resulted, strong and many-flowered spikes being produced 
about this time, some carrying over thirty blooms. In the autumn when 
the bulbs are filling up, alternate waterings with dilute liquid manure 
should be given, more especially those that were not given a shift. C. 
giganteum thrives very well along with these, but is a very shy one to 
bloom : it may also be given a shift now if in need of one. It is not such 
a vigorous growing kind as C. Lowianum, and therefore less pot room 1s 
needed ; it is as well perhaps to remove this species to a drier and warmer 
house when about to flower, as this usually takes place during winter when 
light and heat are ata premium. The same remark applies to C. grandi- 
florum and Tracyanum. C. eburneum, Mastersii, and elegans may also be 
attended to now: with the first mentioned two top-dressing is preferable to 
re-potting when the drainage is known to be in good condition, picking out 
the old compost down to the crocks and replacing with a mixture of two 
parts peat, one fibrous loam, and the other chopped moss and silver sand or 
finely broken crocks. _C. elegans may have a similar soil to that given to 
C. Lowianum. They should be grown a trifle warmer, say along with the 
Masdevallias, and watered freely during the season, but sparingly during the 
winter months. 
Whilst writing of cool Orchids it may be as well to dwell for a short time 
ona very much neglected class of plants, namely, the Barkerias. These, when 
given the right position and treatment, well repay what little attention they 
need. They are best grown in suspended pans, to the wires of which the 
stem-like pseudo bulbs may be tied, thus doing away with the necessity of 
using stakes or twigs. Just now they are beginning to break from the 
central portion of the last made growth, and should some time this month
